hi, everyone:
Just like the code as below:
1 #include <algorithm>
2 #include <stdio.h>
3
4 #pragma pack(push, 1)
5 typedef struct _test_c
6 {
7 char m;
8 int data[10];
9 }test_c;
10 #pragma pack(pop)
11
12 int main()
13 {
14 printf(" sizeof test_c is %d \n", sizeof(test_c));
15 test_c test;
16 for(int i=0; i<10; i++)
17 test.data[i] = 9-i;
18 //int data[10]={9, 8, 7, 6, 5, 4, 2, 3, 1 , 0};
19 std::sort(test.data, test.data+10);
20
21 return 1;
22 }
This code can work on X86, but cause bus error runing on Davinci(My
board is DM6446, GCC 3.4) .
I know the problem is:
std::sort(test.data, test.data+10); test.data is not 4-Bytes aligned.
The software I want to port uses structs liking "test_c" a lot.
Could anyone give me some advice ?
